- from the truck which forms a common mounting for adjacent ends of car bodies.

An important object of the invention is to provide a construction which will at once support the vestibule independently of the car bodies, maintain the balance of the vestibule and resist displacement thereof-at all times and which will insure coordination of the movements of the vestibule and the truck so that the vestibule will remain in the proper position with relation to the cars.

A still further object 'of t-he invention is the provision of a structure of this character permitting the vestibule to be bolted to the truck and providing a construction wherein the weather stripping associated with the vestibule may be carried entirely by the vestibule and simply guided from the can A still further object of the invention is the production of a structure lofr this character which may be relatively cheaply produced and in which the installation and removal of the vestibule are facilitated.

These and other objects we attain by theV construction shown in the accompanying drawings wherein, forthe purpose of illus tration, we have shown a preferred embodiment of our invention and wherein:

Fig. 1 is a plan View of a vestibule mount ing for articulated cars constructed in accordance with our invention; l

Fig. 2 is a vertical sectional view on line 2-2 of Fig. 1; and

Fig. 3 is a semi-diagrammatic View showing the vestibule structure in position between connected cars.

Referring now more particularly to the drawings, the numeral 10 generally designates a truck bolster supporting the adjacent endsV of, cars 11 and providing a'lpivotal mounting therefor. In the present illustration the supporting construction employed is substantially identical with that illustratedin the application of l/Valter S. Adams for patent on pivot for articulated cars tiled August 19, 1928, Serial'No. 298,527, now Patent No.

192e. Vserial No. 389,004.

1,732,998, granted October 22, 1929, each car 11 being equipped with a socket-engaging element 12 extending into a socket 13 formed in a bloclr 14 mounted upon a plate 15 having an annular retaining liange 16. The sole difference between the structure of plate 15, as illustrated in the application aboveidentiiied and the present structure lies in the fact that this plate is formed at its center with an upstanding hub-forming flange 17. Y The hub-y forming flange 17 and peripheralor retaining iange 16 combine to produce 'an annular channel within which the blocks 14 are rotatable so that the effective pivotal connection of the car lies at the center of the plate 15.

r)This hub together with a truck bolster are provided with aligned bores permitting'loose passage of a hing bolt 18. Thevestibule 19 embodies acentralV casting' 20 having a squared polygonal socket 21 to receive and lit the head of king bolt 18. Between the bottom of this casting and the upper end of hub flange 17 a spring 22y surrounds the king bolt, said spring being compressed in installationl to a load in excess of the vestibule weight and possible passenger loads imposed thereon. The lower end of the bolt is keyed as at 23 against rotationwith relation to the truck bolster so that the bolt 18 will turn with'the j truck and through its head and plate 20 will turn the vestibule therewith. I The loose mounting of the bolt in its bore with the truck Y and hub Vflange 17 will permit necessary oscillation of the vestibule aboutl the pivot formed' by key 23 to accommodate normal relative movements of the cars 11 and spring l 22 will act to return the vestibuleto its normal position whendisplaced and to retain it at all times in such normal position. j' i By mounting the vestibule in'thismanner, space is provided beneath the vestibule for the convenient mounting of springs 2li# which engage the ylower ends of weather stripping 25'to maintain thisV weather stripping against. the vestibule frame. Byemploying a similar mounting at'the top of the car theuse of compression springs with the strip guides 2t of the car body where they are relativelyin-v accessible is eliminated, a longer spring canVV L be-employed so that more efficient operation v tated.

Y hereinafter claimed.

of the Weather stripping may be had and the e installation of the stripping is greatly facili- Springs 24 may conveniently have their inner ends secured to casting 2O as at 27.

It Will beobvious tliat'a structure, of this character may be convenientlyrandV cheaply manufactured and at the same time aiords all the advantages afforded bythe ordinary vestibule mounting. It Will also be obvious that this structure is capable ofa considerable range and change of modificationV Without departing from the spirit of my invention, We

accordingly do not limit ourselves to the spe-- cific mounting herein illustrated except as We claim: n 1i.
